To all. colto/m, t may concern:

Be it known that I, RUDOLF PFENNI'NGER, a citizen of the Republic ofSwitzerland, re-

siding at Belleville, in the county of Dane and State of Wisconsin, haveinvented a new and useful Improvement in Panic-Proof invention toprovide La form ofk door which will be rigidly held in closed position,but by the operation of its handlemembers may readily be opeiiedto swingin either direction and from pintles on either of its two longitudinaledges.

specimen, a Shouid be noted that a is' the object of the invention toprovidesuch a hinge and locking mechanism and operating means thereforas Ato insure'the opening of the door, whether the operating lever orhandle be turned inone direction or the other, or whether the door bepushed or.l

pulled. v f

It is a further object of the invention to provide, in connection withthe hinging and locking mechanism referred to, means .by

which the door maybe readily detached ,and bodily removed fiom itsframe.

Other objects and advantages of my invention will appear more fully fromthe'following detailed description of one form of door embodying theinvention.y In this description reference will be had to ,the accom# anino drawin s in which- Figure 1 is a section of a being shown in closedposition and mounted in a frame in a building wall, certain parts beingshown in elevation; Fig'. 2 is an enlarged section of a portion of thedoor shown in Fig. 1 ;l Fig-Bis an enlarged section on the i line 3 ofFig. 2; Fig. 4 is an venlarged section on the line 4 of Fig. 1, themiddleportion of the door being broken out;.Fig. 5 is an enlargeddetailed section of oneof the lower securing'bolts of the doorV taken onthe line 5 lof F ig; 1; Fig. k6 is an enlarged p door constructed f inaccordance with my invention, the door perspective view Ofasecuringbolt'or pintle,-A

y vReferring more particularly'jto thefdr'awwall in 'which is mounted arectangular door ing, ythe numeral 10 designates a building frame 11having'upper and lower transverse Y v members 12 and 1 3, respectively.

The door properk ofl my invention com- Fig. 4)., spaced apart by'tlie'boards 16 vand having their outerjlongitudinal edges joinedy bystrips 17flwhich `have curved outer faces to permitofthe swinging of thedoor, as

- prises front andrear face members 15 v(see willlater appear. TosecureVK the door with-v in its frame, I provide'combined pintle andfastening members of thel formr shown in Fig.'- 6 and*V comprising bolts18 which lie within longitudinal hollow sections 19 `formed bythe spacedfront and rear face,

members 15 and the filler block or board 16 and secured and guidedwithin suchrecess by angular brackets 20 (see FigVl). The

Vouter en'dof each bolt 18 is provided withasquared' portion 21 whichAcompletely fills and is yguided by the walls of the recess 19, eachsquared portion carrying a pintle 22,

4the `end of which is beveled or curved, as

The bolts 18 are Aconstantly shown at 22. urged outward by means ofcompression springs'23, which encircle the bolts and are confinedbetween'washers 24 pinned there- Y on, and the central brackets 20.

f Secured tothe inner' end of each of the bolts 18 is a cable member 25which passes inwardly through the recess 19 and around a pulley orroller 26, which may be shrouded LVby a frame 27 to prevent thecablefrom running' oif. From the pulleys 264 the cablesV run inwardlythrough conduits 28 formed. by spacing" apart the middle filler blocks16 Vandare secured at their inner ends to the ends'ofa centralrack-bar`29, which'is slid-' t able within the conduit 28. Above thefrackbary there is mounted afpinion .30 which is carried bythe squaredportion 31 of a shaft -32-fwhich extends through from one Vface of "the"door'to the other, and is providedonits Y ends with operating handles orknobs 33. AA74 lock 34, mounted withinthe doorand bee low the rack-bar29, is provided with a locking' bolt member'35 which maybe engaged vwitharecess 36 in the lowerV face of `the v s Yra ':kbar, the locking"bolt being adapted to fthr ughkeyholes in the two faces ofthe 'e door.:

If, therefore,after, the door has been opened, the pinion ,30 be rotatedy in the`proper direction, the pintles 22 'which serve as khinge members maythemselves be withdrawn from the re` cesses 38,' and the door may bebodily removed from the frame'. 'At the same time,

the latch plates 39 will prevent such disenmay also be noted that if thepinion 30 be provided with teeth upon a part of its circumference only,the cables 25 may be relieved of all undue strain such as mightbe set upby an attempt to' turn the knobl beyond its proper position, suchturning being prevented by an engagement of the uncut surface of thepinion with the rack-bar.v
